Design and Implementation of A Smart Power Terminal Based on DSP
In order to realize the electrical information collection and remote control of small electrical equipment at municipal, commercial areas and residential buildings for smart grid, a novel design of smart power terminal based on DSP is proposed in this paper. The paper first describes the role of the smart power terminal in the interaction of energy-flow and information-flow between the electrical equipment and distribution network, and then the design of hardware and software is described in details. The hardware system adopts modular design, including the processing core of DSP, signal measurement, wireless communication, load control and power supply, etc. In the design of the wireless communication module, WiFi technology is applied to reduce the difficulty and cost of connecting to the Internet. And the differential amplifier and quasi synchronous sampling technology is also used to effectively improve the accuracy of the single phase signal measurement. Finally, the experimental prototype test results validate the effectiveness of the design.
